The document discusses upgrading OpenStack from Grizzly to Havana. It provides instructions on removing old packages, installing new packages, migrating databases, and upgrading components individually to minimize downtime. The process involves updating packages on control, network, and compute nodes, migrating the database, and some clean-up steps.
OpenStack services can be containerized to provide a more lightweight and portable deployment option compared to virtual machines. The document discusses how OpenStack services like Nova, Neutron, Cinder etc. run as individual containers that share the host operating system and can be configured by modifying files in a shared directory. Logs and operations like start/stop/restart can also be managed from the host through the container IDs. Overall, containerization allows OpenStack deployments to benefit from advantages like agility, density and simplified operations.

This document discusses Google Cloud Platform's approach to managing the lifecycle of Kubernetes clusters, including setting up, upgrading, and decommissioning clusters. It outlines problems with the existing "kube-up.sh" tool and motivates the need for new cluster lifecycle management tools. These should make cluster setup and management more declarative, portable across clouds, and support additional use cases and customization needs. The presentation provides examples of how tools could better support tasks like provisioning certificates and deploying networking in a standardized way.
This deep dive will address the questions on how to install, deploy and operate OpenStack by providing informative slides which will help users get ahead start with this awesome project
This document discusses using OpenStack for VDI (Virtual Desktop Infrastructure). It provides an example of a large company, Ctrip, that uses OpenStack VDI for over 10,000 agents with over 200,000 daily connections. Key technical issues with OpenStack VDI are then outlined, including provisioning, connection protocols, cloud-init configuration, boot storms, and the need for automation. Automation is discussed as being critical but challenging for tasks like backups, password recovery, and resource management.
In this slide, I briefly introduce the container and how docker implement it, including the image and container itself. also show how docker setup the networking connectivity by default bridge network.
The slides give the brief idea of the current situation of the container orchestration integration in OpenStack and how OpenStack Kuryr can improve the situation.
An Updated Performance Comparison of Virtual Machines and Linux ContainersKento Aoyama
The document compares the performance of virtual machines (KVM) and Linux containers (Docker) by running benchmarks that test CPU, memory, network, and file I/O performance. It finds that Docker containers perform comparably to native Linux for most benchmarks, while KVM virtual machines have higher overhead and perform worse than Docker containers or native Linux for several tests, especially those involving CPU, random memory access, and file I/O. The study provides a useful comparison of the performance of these two virtualization technologies.
This document discusses using plain Linux bridges for networking Docker containers on Kubernetes clusters deployed on OpenStack. It involves pre-allocating IP addresses on virtual machines, configuring Docker bridges to use the pre-allocated subnet, and allowing Kubernetes pods and containers to use the pre-allocated IP addresses for networking. The approach aims to provide a simple networking solution that is compatible with legacy systems.
This document provides steps to deploy a WordPress application with a MySQL database on Kubernetes. It demonstrates creating secrets for database credentials, persistent volumes for database storage, services for external access, and deploying the WordPress and MySQL containers. Various Kubernetes objects like deployments, services, secrets and persistent volumes are defined in YAML files and applied to set up the WordPress application on Kubernetes.
The document discusses Kubernetes networking. It describes how Kubernetes networking allows pods to have routable IPs and communicate without NAT, unlike Docker networking which uses NAT. It covers how services provide stable virtual IPs to access pods, and how kube-proxy implements services by configuring iptables on nodes. It also discusses the DNS integration using SkyDNS and Ingress for layer 7 routing of HTTP traffic. Finally, it briefly mentions network plugins and how Kubernetes is designed to be open and customizable.
This document compares the performance of KVM and Docker instances in OpenStack. It finds that for boot and delete operations, KVM is around 20% faster than Docker at high concurrency levels. For CPU and memory tests at low concurrency, KVM is 2-10% slower than bare metal, while Docker is 2-5% slower. For sequential and random read/write file I/O tests, KVM is similar or slightly slower than bare metal, while Docker is slightly slower than KVM. Overall performance decreases for both KVM and Docker as concurrency increases.

CloudStack vs OpenStack vs Eucalyptus: IaaS Private Cloud Brief Comparisonbizalgo
This document compares the architectures, installation processes, administration tools, security features, and high availability capabilities of CloudStack, Eucalyptus, and OpenStack. CloudStack has a monolithic controller architecture and the easiest installation process. Eucalyptus closely mimics AWS but has a more difficult multi-component installation. OpenStack is the most fragmented with many interdependent pieces and a challenging installation. All three provide basic security through VLANs and firewalls, with Eucalyptus and OpenStack adding additional authentication. High availability varies by platform, with CloudStack using a load-balanced controller, Eucalyptus relying on component failover, and OpenStack's Swift storage using replication across its ring topology.
This document compares different open source cloud computing platforms and their features. It lists several hypervisor and cloud management platforms including Xen, KVM, Eucalyptus, OpenStack, OpenQRM, OpenNebula, XenServer, Oracle VM, and CloudStack. For each it indicates whether they support various hypervisor technologies like Xen, KVM, LXC, and VMware. It also provides information on the licensing, plugins, and APIs supported by each platform. The document then details the architecture and components of OpenStack including Nova, Swift, and Glance. It lists URLs and credentials for accessing demo OpenStack and OpenQRM installations. Finally, it outlines additional features of the commercial OpenQRM Enterprise edition over the open source version
CloudStack has a monolithic architecture and medium difficulty installation. It offers good administration through a web UI and EC2 API compatibility. High availability is achieved through load balancing multiple controller nodes. Eucalyptus closely mimics AWS with 5 main components and medium difficulty installation. It is administered primarily through EC2 compatible CLIs. High availability relies on failover between primary and secondary component nodes. OpenStack has a fragmented architecture into many services and difficult installation due to choices and lack of automation. Administration uses a web UI, EC2 tools, and native CLIs. Security uses Keystone authentication. High availability is achieved primarily through Swift's disk replication "ring", otherwise manual configuration is needed.

Tuesday, July 30th session of the vBrownBag OpenStack Sack Lunch Series: Couch to OpenStack. We cover Nova, the Compute Service that deploys and runs VMs.
Quantum provides an API for managing virtual networks in OpenStack. It allows tenants to create multiple private networks with their own IP addressing, and attach virtual machines to these networks. Quantum uses a plugin architecture that supports various networking technologies by exposing a generic API and allowing operators to choose different backend implementations, such as VLANs, VXLAN, or SDN controllers. This provides tenants with advanced network automation capabilities and operators with network technology choices.
This document discusses using Puppet to deploy OpenStack. Puppet is a configuration management tool that can be used to automate and standardize the deployment of OpenStack. The Puppet modules for OpenStack provide classes and definitions that can be used to configure different OpenStack components like Nova, Glance, Keystone, etc. in a repeatable way. Puppet enforces the desired state by comparing the current and desired configuration and making necessary changes. This allows OpenStack to be deployed reliably using best practices defined in the Puppet modules.
DockerCon14 Performance Characteristics of Traditional VMs vs. Docker ContainersDocker, Inc.
Docker containers provide significantly lower resource usage than traditional virtual machines when running multiple workloads concurrently on a server.
When booting 15 Ubuntu VMs with MySQL sequentially, Docker containers finished on average 3.5 seconds per boot versus 5.8 seconds for KVMs. Docker usage of CPU, memory, and load average was also much lower when running the same workload on 15 VMs concurrently in a steady state. Specifically, Docker CPU usage averaged 0.2-0.3% versus 1.9-0.4% for KVM, with Docker using 49MB of memory per VM versus 292MB for KVM.
With more than 140 million users, KakaoTalk is the most popular mobile messaging platform in South Korea. The team at daumkakao has been using OpenStack with the intention for tranforming the current legacy infrastructure into scale out based cloud to build and offer new services for its users. In this session, we'd like to share our experiences with the OpenStack community, specifically in regards to meeting our needs for networking with Neutron.OpenStack Neutron offers a lot of methods to implement networking for VMs and containers. For production operations, VM migration can be a common activity to manage resources and improve uptime. It's not hard using shared storage like Ceph, but network settings, such as IP addresses need to be preserved. With a shared storage environment, an image can be attached anywhere inside of a data center, but a service IP for a virtual machine is different story. And when you don't use the floating IPs, keeping the same IP across a data center-wide set of VLANs is hard job.To maintain a virtual machine's IP settings and balance IPs between VLANS, we tried several options including overlay, SDN, and NFV technologies. In the end we came to use a route-only network for our virtual machine networks, leveraging technology like Quagga for RIP, OSPF BGP integrated with Neutron.
Capistrano is a tool for automating tasks on remote servers. It executes commands in parallel on targeted machines and provides rollback of changes. Capistrano uses Net::SSH, Net::SFTP, and Net::SCP to automate tasks over SSH, and supports features like task chaining, streams, prompts, roles, and detecting/rolling back broken jobs.
In this talk Jiří Pírko discusses the design and evolution of the VLAN implementation in Linux, the challenges and pitfalls as well as hardware acceleration and alternative implementations.
Jiří Pírko is a major contributor to kernel networking and the creator of libteam for link aggregation.
Performance characteristics of traditional v ms vs docker containers (dockerc...Boden Russell
Docker containers provide significantly lower resource usage and higher density than traditional virtual machines when running multiple workloads concurrently on a server.
When booting 15 Ubuntu VMs with MySQL sequentially, Docker containers boot on average 3.5 seconds compared to 5.8 seconds for KVMs. During steady state operation of 15 active VMs, Docker uses on average 0.2% CPU and 49MB RAM per container, while KVMs use 1.9% CPU and 292MB RAM each. Docker maintains low 1-minute load averages of 0.15, while KVMs average 35.9% under load.
KVM and docker LXC Benchmarking with OpenStackBoden Russell
Passive benchmarking with docker LXC and KVM using OpenStack hosted in SoftLayer. These results provide initial incite as to why LXC as a technology choice offers benefits over traditional VMs and seek to provide answers as to the typical initial LXC question -- "why would I consider Linux Containers over VMs" from a performance perspective.
Results here provide insight as to:
- Cloudy ops times (start, stop, reboot) using OpenStack.
- Guest micro benchmark performance (I/O, network, memory, CPU).
- Guest micro benchmark performance of MySQL; OLTP read, read / write complex and indexed insertion.
- Compute node resource consumption; VM / Container density factors.
- Lessons learned during benchmarking.
The tests here were performed using OpenStack Rally to drive the OpenStack cloudy tests and various other linux tools to test the guest performance on a "micro level". The nova docker virt driver was used in the Cloud scenario to realize VMs as docker LXC containers and compared to the nova virt driver for libvirt KVM.
Please read the disclaimers in the presentation as this is only intended to be the "chip of the ice burg".
In this slide, we discussed the IPVS, including the introduction, demonstration, implementation, and integration in Kubernetes.
IPVS was based on the netfilter and we discussed how it works with iptables and also compares the detail implementation in Kubernetes to show why IPVS has a better performance in IPTABLES.
